I just read some articles about the SMART-1 research satellite at the European Space Agency's website.
It's been orbiting the moon for the past three years or so, carefully
mapping the moon's surface, testing its solar powered thruster, and
other scientific-y stuff like that. Anyway, the mission came to an end
four days ago, on September 3rd, when the satellite was deliberately
crashed into the surface of the moon. Is that for real? Doesn't that
suck for the moon? I mean, I don't know if you've ever looked at
close-up photographs of the moon's surface, but it's real pretty up
there. And now there's about 630 pounds of space garbage littering the
surface of the moon that wasn't there before. How long's it going to be
just sitting there, looking all messy, before someone goes there to
tidy up?

I get pretty annoyed whenever I see someone toss a cigarette out a
car window, like the Earth is their own personal trash can. To me this
is just a bigger, more moon-oriented example of the same idea.
According to the European Space Agency, "SMART-1 ended its journey in
the Lake of Excellence region, in the point situated at 34.4° South
latitude and 46.2° West longitude." Okay guys - apparently you know
exactly where you crashed it - now go clean it up!
